DETAILED DESCRIPTION

As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

Embodiments disclosed herein include skin treatment apparatuses which include a cooling member, such as for providing cooling of the skin following dermal treatments, such as abrasion or exfoliation. For example, cooling of the skin may be beneficial in tightening and sealing the skin while reducing any redness and puffiness. The embodiments described herein conveniently and advantageously provide a cooling function for the skin within the same apparatus as the dermal treatment function.

With reference first to FIGS. 1-6, a microdermabrasion apparatus 10 is illustrated. The microdermabrasion apparatus 10 includes a housing 12 and a microdermabrasion treatment head 14 attached to the housing 12, where the microdermabrasion apparatus 10 can be received in a charging base 16 as shown. In one or more embodiments, the housing 12 may be elongated and generally curved to facilitate gripping by a user and ergonomic access to the user interface, described further below. The charging base 16 may be generally cylindrical and formed with a recess 18 (FIG. 6) for receiving at least a bottom end 20 of the housing 12 of the microdermabrasion apparatus 10. Although a particular shape of the housing 12 and charging base 16 are illustrated, it is understood that the microdermabrasion apparatus 10 is not limited to these shapes.

The microdermabrasion treatment head 14 may be generally cylindrical with a hollow interior. The microdermabrasion treatment head 14 has a top rim 22 which may comprise a microcrystalline or diamond material, wherein the top rim 22 may be placed against a user's skin and moved across the surface of the skin to provide exfoliation while suction (described below with reference to FIG. 16) is applied. As shown, the microdermabrasion treatment head 14 may be received on the housing 12 so as to extend forward of or offset from a longitudinal central axis A-A of the housing 12, wherein this position may facilitate and optimize contact of the microdermabrasion treatment head 14 with a user's face. The microdermabrasion treatment head 14 may be integral with the housing 12, or may be removably secured to a top end 24 of the housing 12 via a snap fit, slidable or threaded connection, for example.

The microdermabrasion treatment head 14 and suction act to exfoliate the skin, removing dead cells from the skin surface, revealing and stimulating the fresh skin layer beneath. The microdermabrasion apparatus 10 can function to restore youthful radiance to the skin, improve skin tone and texture, smooth the appearance of fine lines and wrinkles and reduce the appearance of age spots and sun damage. Multiple removable and interchangeable microdermabrasion treatment heads 14 with top rims 22 having different surface characteristics, and therefore different sensitivities, may be included for use with the microdermabrasion apparatus 10.

In one or more embodiments, the microdermabrasion apparatus 10 is rechargeable and includes an internal rechargeable (e.g. lithium) battery 26 (FIGS. 15 and 16). FIGS. 6 and 7 illustrate induction charging points 28 on the housing 12 and the interior of the charging base 16 as well as a charging port 30 on the exterior of the charging base 16. To charge the microdermabrasion apparatus 10 via induction charging, the bottom end 20 of the housing 12 may be inserted into the recess 18 of the charging base 16, and the charging base 16 is connected to an electrical outlet or other power source by a charging cord (not shown) received in the charging port 30. Alternatively, the charging port 30 may be provided on the housing 12 for directly charging the microdermabrasion apparatus 10, such that the charging base 16 would not be required.

FIG. 8 is an inverted front perspective view of the microdermabrasion apparatus 10 illustrating a cooling member 32 such as a cooling plate provided on the bottom end 20 of the housing 12 of the microdermabrasion apparatus 10. The cooling member 32 may be used to contact and cool skin within a treatment area after exfoliation by the microdermabrasion treatment tip 14, or may be generally used for cooling the skin at other times or in other regions. In one or more embodiments, the cooling member 32 may be constructed from a metallic material and may be cooled by a thermoelectric cooler or Peltier device or Peltier chip 34, as illustrated in FIG. 15. In a non-limiting example, the cooling member 32 may be capable of reaching a temperature less than 9 degrees C. in less than 60 seconds and between approximately 0-9 degrees C. in an elapsed time of 60-150 sec. The cooling member 32 can be generally planar and circular- or oval-shaped as shown or could alternatively have other shapes and/or textures.

As is known in the art, thermoelectric coolers may operate by the Peltier effect, which creates a temperature difference by transferring heat between two electrical junctions. A Peltier device has two sides, and a voltage is applied across joined conductors to create an electric current. When a DC electric current flows through the Peltier device it transfers heat from one side to the other so that one side gets cooler while the other gets hotter. The “hot” side is attached to a heat sink 36 (FIGS. 15 and 16) so that it remains at ambient temperature, while the “cool” side is below room temperature. In operation, the cool side absorbs heat which is then transferred to the hot side of the Peltier device. In some instances, multiple thermoelectric coolers may be connected and placed between two metal or ceramic plates.

As an alternative or in addition to the integral cooling member 32 or cooling plate described above, a removable cooling treatment head 38 having a cooling member 32 may be provided. FIGS. 9-14 illustrate another embodiment of the microdermabrasion apparatus 10 which includes a removable cooling treatment head 38 which is interchangeable with the microdermabrasion treatment head 14. In this embodiment, after exfoliation of skin within a treatment area using the microdermabrasion treatment head 14, the head 14 can be interchanged with the cooling treatment head 38 which can then be applied to cool skin within a treatment area. Alternatively, the cooling treatment head 38 may be generally used for contacting and cooling the skin at other times or in other regions. As above, the cooling member 32 on the removable cooling treatment head 38 may be constructed from a metallic material and may be cooled by a Peltier chip 34, wherein the Peltier chip 34 may be disposed within the housing 12 or within the cooling treatment head 38 itself. Also, as above, the cooling member 32 on the cooling treatment head 38 can be generally planar and circular- or oval-shaped as shown or could alternatively have other shapes and/or textures.

The microdermabrasion apparatus 10 includes a power button 40 which can function to turn the microdermabrasion apparatus 10 on and off as well as to toggle through different treatment levels. A controller or printed circuit board (PCB) 42 in electrical communication with a vacuum pump 44 (FIGS. 15 and 16) can provide multiple suction intensity levels through the microdermabrasion treatment head 14 to provide optimal comfort and effectiveness to a user. Different suction levels may be used for different areas of the face, for example, where a lower suction level may be recommended around the sensitive eye area while a higher suction level may be possible around the forehead and nose areas. In one non-limiting example, different suction levels of the vacuum pump 44 may include: Level 1: 1.0-1.9 L/min; Level 2: 1.6-2.3 L/min; Level 3: 2.0-2.8 L/min; Level 4: 2.6-3.4 L/min.

Indicator lights 46, such as LEDs, may be provided to indicate when the microdermabrasion apparatus 10 is powered on and to indicate the selected treatment level. The indicator lights 46 may also be used to indicate charging progress of the battery 26. The microdermabrasion apparatus 10 can also include a cooling power button 48 for powering the cooling member 32, either integrally formed on the bottom end 20 of the housing 12 of the microdermabrasion apparatus 10 or removable attached via the cooling head 38, on and off as well as a corresponding cooling mode indicator light 50.

Turning now to FIGS. 17-22, a dermaplaning apparatus 60 is illustrated. The dermaplaning apparatus 60 includes a housing 62 and a trimming head 64 which includes a blade or blade assembly 66, where the dermaplaning apparatus 60 can be received in a charging base 68 (FIG. 21). In one or more embodiments, the housing 62 may be elongated in shape, such as to facilitate gripping by a user. The trimming head 64 may be integral with the housing 62 or may be removably secured to a top end 69 of the housing 62 via a snap fit, slidable, or threaded connection, for example. The blade assembly 66 may likewise be removable from the trimming head 64. The charging base 68 may be generally cylindrical and formed with a recess (such as recess 18 illustrated in FIG. 6 for charging base 16) for receiving at least a bottom end 70 of the housing 62 of the dermaplaning apparatus 60. Although a particular shape of housing 62 and charging base 68 are illustrated, it is understood that the dermaplaning apparatus 60 is not limited to these shapes. The dermaplaning apparatus 60 can be used to provide exfoliation of skin within a treatment area, wherein the trimming head 64 with its vibrating blade 66 are moved across a user's skin to gently remove dead skin cells and unwanted hair on the surface of the skin, thereby improving a user's complexion.

In one or more embodiments, the dermaplaning apparatus 60 is rechargeable and includes an internal rechargeable (e.g. lithium) battery 72 (FIGS. 21 and 22). Induction charging points (not shown) may be provided on the housing 62 and the interior of the charging base 68, and a charging port 74 may be provided on the exterior of the charging base 68. To charge the dermaplaning apparatus 60 via induction charging, the bottom end 70 of the housing 62 may be inserted into the recess of the charging base 68, and the charging base 68 is connected to an electrical outlet or other power source by a charging cord (not shown) received in the charging port 74. Alternatively, the charging port 74 may be provided on the housing 62 for directly charging the dermaplaning apparatus 60, such that the charging base 68 would not be required, as illustrated in FIG. 18.

FIG. 20 is a side perspective view of the bottom end 70 of the housing 62 of the dermaplaning apparatus 60 illustrating a cooling member 76 such as a cooling plate provided on the bottom end 70 of the housing 62. The cooling member 76 may be used to contact and cool skin within a treatment area after exfoliation by the blade assembly 66, or may be generally used for cooling skin at other times or in other regions. In one or more embodiments, the cooling member 76 may be constructed from a metallic material and may be cooled by a thermoelectric cooler or Peltier device or Peltier chip 78 with a heat sink 80, as illustrated in FIGS. 21 and 22 and as described above with respect to the microdermabrasion apparatus 10. In a non-limiting example, the cooling member 76 may be capable of reaching a temperature less than 9 degrees C. in less than 60 seconds and between approximately 0-9 degrees C. in an elapsed time of 60-150 sec. The cooling member 76 can be generally planar and circular- or oval-shaped as shown or could alternatively have other shapes and/or textures.

The dermaplaning apparatus 60 includes a power button 82 which can function to turn the dermaplaning apparatus 60 on and off as well as to toggle through different treatment levels. A motor assembly 86 having an eccentric load is disposed with in the housing 62 (FIGS. 21 and 22) and is operably connected to the blade assembly 66 for generating vibration of the blade 66. A controller or PCB 84 in electrical communication with the motor assembly 86 for providing multiple vibration intensity levels of the blade 66. In one non-limiting example, different speeds of the motor 86 may include a low speed (e.g. 6400 RPM +/−5%) and a high speed (7700 RPM +/−5%) which translate to different blade vibration frequencies. The power button 82 may also be used to power the cooling member 76 on and off.

Indicator lights 88, such as LEDs, may be provided to indicate when the dermaplaning apparatus 60 is powered on and to indicate the selected treatment level. The indicator lights 88 may also be used to indicate charging progress of the battery 72 and the power status of the cooling member 76.
